Question Fuel Level Off

My fuel gauge has been acting weird now for the past few months and it's now to the point where I need to do something about it. Most of the time it'll show the actual fuel level and sometimes it'll say I'm empty even though I know I have fuel. It's read empty twice right after I just put fuel in it. It only changes when I turn the car off and back on. By that I mean if I start the car and it reads empty, it'll continue to show empty until I turn it off and back on then it usually reads the proper level. So I'm thinking it's either a faulty fuel gauge or my fuel level sensor is going. But I figured if it was the sensor, I'd get CEL with a code but I could be mistaken. What do you guys think? Any help is greatly appreciated.

You will not get a code for sending unit. When the gauge reads empty do you also get the DIC message "low fuel"?

If you get both at the same time it isn't your dash gauge. You probably have a bad connection back at the tank since these 2 are seperate sensors, but with common power.

Mkay, that makes feel a little better. I'll poke my head under there and see if I can find it and let you know. Thanks for helping Coby.

Check the ground wire.

2004-2006 f-150's were horrible for this and it was because the ground wire would break coming from the pcm and now and again it would touch and give you a proper level, was easily fixed by attaching the ground wire to the frame instead.

so basically im saying I agree with coby on the ground issue

2017 F150 XLT-XTR - 5.0L, 4x4, 3.55's, E-locker, xtr chrome package, fx4 off-road package.
20/25 imp mpg

I checked the ground and it seems good. Also took it to a friend who used to work for Chevy and did a gauge test to rule that out also. Didn't have him look too much into it since he was busy, but he suggested that it is the fuel level senor going bad.

Sorta irrelevant but when i plug in my scan tool, it shows the % of fuel you have left in your tank with these cars. Once in awhile i plug it in just to see if my 02 sensor and fuel trim info. Great tools to help diagnose things.
